Mixed Messages Project: Life Advice

Hello. My project is called Life Message which which produces advices about life.
The JavaScript part was pretty easy. I just need to make arrays of messages and then for a random message with random sentence from each array. The HTML took up a chunk of the coding, as well as the CSS. What I really saw as the primary challenge in this project is to have made the website, specifically meaning the HTML button, interactive through JavaScript.
